What are the criteria and procedure for CE marking of LCDs and which institutions can I contact? A liquid crystal display is a kind of flat panel display. It is used for the screen display of televisions and computers. The advantages of this display are low power consumption, small size, and low radiation. The LCD uses a liquid crystal solution in two polarized materials, so the current flowing through the liquid causes the crystals to rearrange themselves to achieve the purpose of the image. If you need to apply for CE certification, you can contact our company BEST ONE Inspection for the procedure.
The need for CE marking
CE marking provides a single technical specification for products from all countries for trade in the European market and simplifies trade procedures. In order to enter the European Union and the European Free Trade Area, products from all countries must be CE certified and have the CE mark on the product. CE marking is therefore the passport for products to enter the EU and EFTA markets.
CE certification means that the product meets the safety requirements set out in the EU Directive; it is a company’s commitment to consumers and increases their confidence in the product; products bearing the CE mark reduce the risk of being sold on the European market.
Test items for LCD CE certification
- EMC-EN55015.
- EMC-EN61547.
- LVD-EN60598.
- EN61347.
- EN61000-3-2/-3 (testing of harmonics).
CE consists of EMC (Electromagnetic Compatibility) + LVD (Low Voltage Directive), EMC also includes EMI (interference) + EMC (anti-interference), LVD is also commonly known as SAFETY safety, general low voltage products AC less than 50V, DC less than 75V can not LVD project. Low voltage products only need to test EMC and issue CE-EMC certificate, high voltage products need to test EMC and LVD and issue two certificates and reports CE-EMCCE-LVD.
Technical documents to be prepared for CE certification of LCDs
- The name and address of the manufacturer (EU authorized representative (EU author) AR), the name and model of the product, etc.
- Manuals for the use of the product.
- Safety design documents (including main design drawings, i.e. design drawings indicating creepage distance, clearance distance, number and thickness of insulation layers).
- product technical conditions (or enterprise standards), preparation of technical information.
- electrical schematics, block diagrams, wiring diagrams, etc..
- List of main components or raw materials (please use products with European certification mark).
- Test report (test report).
- The relevant certificate from the EU authorized certification body NB (for other modes than A).
- the certificate of registration of the product in the EU (for certain products, such as Class I medical devices, general IVD in vitro diagnostic devices).
- CE Declaration of Conformity (DOC).
LCD EU CE certification process
- Fill in the application form, confirm the product name, model, quantity, and other information, and submit the relevant product information.
- Pay for quotation, application form, and information audit for certification.
- When the data audit is passed, the product will be tested and qualified, and a draft certificate will be issued.
- Applicants check the draft, if there are any changes, they return and reissue the draft.
- EU CE certificate is issued.
Advantages of applying for CE marking
- EU laws, regulations, and harmonized standards are not only numerous but also very complex, so seeking the help of an EU notified body is a wise move to save time and effort and reduce risks.
- Obtaining a CE certificate from an EU notified body can largely win the confidence of consumers and market surveillance authorities.
- It can effectively prevent irresponsible accusations from happening.
- In case of litigation, the CE certificate from the EU notified body becomes legally valid technical evidence.
